This system was developed and implemented by the HPRU in collaboration with the SAMRC Information Technology (IT) Services Division and an external developer in 2010.
BCEPS was initially approved by the SAMRC ethics committee in 2010 for use in trials conducted within the HPRU and reviewed again in 2014.
To date, at HPRU, no participant has refused consent or withdrawn from BCEPS.
By addressing the ethical concerns around participant consent and rights, participant confidentiality and privacy, data security and access, and data management and storage, we were able to successfully implement BCEPS at HPRU. There have been no concerns raised by participants or communities regarding its use in our setting.

We conducted a 'needs assessment' at the 7 HPRU clinical research sites (CRSs) to identify criteria for the implementation of a biometric system.
After successful testing, we gained approval from the relevant regulatory authorities and, with the assistance of the MRC IT Department, implemented the BCEPS at the 7 HPRU CRSs in July 2010.
When there was no internet connectivity, a back-up system comprising a laptop loaded with the BCEPS and a 3G card for internet access was available for the HPRU sites.
